Title:
SILICON-CARBON COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR, SECONDARY BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/040605
Kind Code:
A1
Abstract:
The present application relates to a silicon-carbon composite material, comprising a carbon nanotube/porous carbon composite matrix and a silicon-based material. Porous carbon in the carbon nanotube/porous carbon composite matrix is connected to a carbon nanotube by means of a connecting unit. By utilizing the high conductivity and the strong mechanical properties of the carbon nanotube, the overall conductivity, the pressure resistance and the expansion resistance of the silicon-carbon composite material can be improved, so that the cycle performance, the electrode sheet cycle expansion performance and the rate capability of a secondary battery are improved.
